1. Che cosa significa LED?
LED è l'abbreviazione di diodo a emissione di luce.
2. Quanto durano i LED?
LEDs are notable for being extremely long-lasting products. Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!
3. Where can LEDs be used?
They can be used almost anywhere. LED replacements are already available for bulb types such as A-shape, PAR reflectors, MR reflectors, decorative, undercabinet, and more. When used on dimmers, particularly dimming systems that support many bulbs, we suggest testing a few LEDs first to test compatibility.
4. What are the advantages of switching to LED?
The advantages of switching to LED are numerous. Here are just some of the benefits: LEDs use much less electricity than other bulbs, have extremely long rated lives, produce very little heat, do not emit UV or infrared, contain no mercury, are resistant to shock and vibration, and can operate effectively in extremely cold environments.

5. Why do LEDs cost more than other types of bulbs? Are they worth it?
LED is still a new technology, and the expense of producing quality product is still high. However, pricing has come down dramatically from just a few years ago and prices are expected to continue to drop. In terms of whether LEDs are worth the extra cost, it’s helpful to look at the cost to operate a bulb in addition to the up-front cost. The energy savings realized in a switch to LED means that the extra up-front cost is often paid back rather quickly, and you’ll wind up saving money over the life of the bulb. Here is an example: for a residential customer who may have the light on for just 10 hours per week ñ the payback is over 10 years. On the other hand, a retail or restaurant client who is burning lights for 90-100 hours per week will calculate their payback on a $70 LED PAR to be less than 18 months. Taking a look at your payback estimate should definitely be a consideration when deciding if LED is right for you.
6. C'è davvero qualche differenza tra un LED da $ 10 e un LED da $ 50?
Sì. I LED sono molto simili all'elettronica di consumo e la qualità è davvero importante. Affinché un LED funzioni correttamente e fornisca un'emissione luminosa accettabile, tutti i componenti devono essere costruiti per durare. È sempre una buona idea acquistare da un produttore e un rivenditore che sei sicuro che starà dietro il prodotto. Se desideri saperne di più sui componenti e su come i LED prodotti a basso costo si sovrappongono a prodotti di alta qualità.
7. Un LED produrrà abbastanza luce per sostituire la mia attuale lampadina?
Per la maggior parte delle applicazioni, sì. I prodotti LED standard stanno ora sostituendo in modo affidabile gli equivalenti a incandescenza fino a 100 watt e sono disponibili prodotti speciali per sostituire wattaggi ancora più elevati.
8. Qual è la qualità della luce LED?
If you buy quality product, the light quality is excellent. Color Rendering Index (CRI) is generally used to measure light quality on a scale from 1-100. Most LEDs have a CRI rating of at least 80, and many are rated 90 and above.
9. How green are LEDs?
LEDs are very green. For starters, they use much less electricity than many other lighting products. This means that less electricity has to be produced to operate them, and resulting in lower emissions from power plants, especially in areas where coal-fired plants are common. Unlike CFLs, they contain no mercury. Because of their long life, they also reduce solid waste: If you replace an incandescent bulb with an LED, you will prevent fifty 1,000 hour incandescent bulbs from being thrown away. Additionally, they produce very little heat and can reduce energy usage related to HVAC. The U.S. Department of Energy has estimated that increased adoption of LEDs over the next 15 years would also reduce electricity demands from lighting by 62 percent, prevent 258 million metric tons of carbon emissions, and eliminate the need for 133 new power plants.
10. Can LEDs be used with dimmers?
Usually, yes. Many LEDs are specifically listed as being dimmable. Some dimming systems work with LEDs better than others, so it’s best to test one or two before completely re-lamping a space.
11. Should LEDs be used in enclosed fixtures?
Not if they are completely enclosed. In order for an LED to function correctly, they must be in a non-enclosed fixture.
